Thus, the areas A to L are determined as shown in FIG. 6, and the optimum position is determined. If it is determined that the area L (step S7), the HU is determined in step S8.
A master warning is displayed on D. This master warning display is displayed in the master warning display section 5.
5 is performed. If it is determined that the area is the area H (step S9), a master warning is displayed in the meter in step S10. The same determination is made in other areas, and a master warning display is performed in step S12. In this case, for simplicity of illustration, other than the regions L and H, other (step S11) and other display (step S1) are put together.
Although described as 2), in such other areas as well, the areas are determined individually similarly to the areas L and H, and the respective individual master warning displays are performed.

Accordingly, depending on where the occupant is watching the area A to L during driving, a master warning display can be performed in that area in response to this. Therefore, when an alarm state of the vehicle is required due to a decrease in the oil pressure of the engine lubricating oil, the master warning display can be quickly and appropriately recognized.

Further, by recognizing such a master warning display, it is possible to prompt confirmation of each warning lamp on the individual display section 3, and it is possible to quickly and appropriately recognize a place where the vehicle needs an alarm. , You can take quick action.

FIG. 9 shows a control flowchart of the second embodiment.

In this flowchart, the basic steps are the same as those in the flowchart of the first embodiment shown in FIG. 8, and the same reference numerals are given and duplicate explanations are omitted. On the other hand, in this embodiment, when gazing at a specific position during driving,
A master warning is displayed in the discrimination visual field. Therefore, after calculating the driver's gazing point in step S5,
In step S21, it is determined whether or not the user is gazing at a specific position, for example, the front front or the meter. In this determination, when the human gaze is stopped at the specific position for 100 ms or more, it is determined that the user is gazing at the area. If it is determined that the specific position is the front gaze of the front front (step S22), the HUD is determined in step S23.
A master warning is displayed in the upper discrimination field of view.
If the specific position is the meter and it is determined that the user is watching the meter, a master warning is displayed in the discrimination visual field of the meter in steps S24 and S25.

The display in the discrimination visual field is performed, for example, by finding the closest one within a radius of 5 degrees from the point of gazing, among a plurality of master warning displays set in advance at a specific position. It is displayed near 5 degrees. The display at the vicinity of a radius of 5 degrees is for eliminating an unsightly feeling. Further, the display in the discrimination visual field is performed so that the master warning display can be easily and quickly recognized.

The display in the discrimination visual field is performed only at the time of meter gaze and front gaze. This is a gaze state that is extremely important for driving a vehicle, and these gazes are displayed by the master warning display. This is to prevent the state from being interrupted as much as possible. However, it is also possible to display in the discrimination visual field only at one of the gaze of the meter and the front gaze, and further, to display the discrimination visual field at the gaze of another specific position.

If it is determined in step S21 that the particular position is not being watched, another master warning display corresponding to the line-of-sight position is performed in step S26. Therefore, in this embodiment, it is possible to perform the master warning display according to the driver's gaze position, and furthermore, the master warning display can be performed in the discrimination visual field in the state of the front gaze or the meter gaze, and the master warning display can be performed more quickly and reliably. Can be recognized. Further, by displaying the master warning display in the discrimination visual field in front gaze or meter gaze, it is possible to promote front gaze or meter gaze as much as possible.

FIG. 10 is a flowchart according to the third embodiment.

Also in this embodiment, the same steps as those in the flowchart of the first embodiment in FIG. 8 are denoted by the same reference numerals, and duplicate description will be omitted. On the other hand, in this embodiment, when the driver is gazing at the pointer meter, a master warning is displayed on the pointer. In many cases, when a driver looks at a pointer meter, a master warning is displayed in a discrimination visual field by using the pointer. That is, in step S31, it is determined whether or not the driver is gazing at the pointer. If the driver is gazing at the pointer, a master warning is displayed on the pointer in step S32. Thereby, a master warning display can be performed in the discrimination visual field. In this case, the function of the master warning display is performed by changing the hands from white hands to red hands, or by blinking the light of the hands. If it is determined in step S31 that the pointer is not being watched, a master warning display corresponding to the sight line position of the occupant is performed in step S33.

FIG. 11 shows a pointer A displayed as a master warning as described above. That is, the color of the tip B of the pointer A has changed. As a result, when the driver is gazing at the pointer meter, the master warning display can be easily performed in the discrimination visual field.

FIG. 12 is a flowchart according to the fourth embodiment.

Also in this flowchart, the same reference numerals as in the flowchart according to the first embodiment of FIG. 8 denote the same parts, and a repetitive description will be omitted. On the other hand, in this embodiment, when there is no master warning display portion in the driver's discrimination field of view, the brightness of the master warning display is increased to make it easier to notice. That is, in step S41, it is determined whether or not there is a master warning display section within the discrimination field of view of the driver. If it is determined that there is no master warning display part in the discrimination visual field, a master warning warning display is changed in step S42. Next, in step S43, a master warning display is performed, and the brightness of the display is increased or blinked, and further, a change such as increasing the display state or changing the color is performed. Conversely, if it is determined in step S41 that there is a master warning display section within the driver's discrimination field of view, a master warning display without changing the display is performed in step S44. Therefore, according to this embodiment, the master warning display can be easily noticed even when there is no display portion in the driver's discrimination visual field and the master warning display must be confirmed in the peripheral visual field. Therefore, it is possible to reduce the number of master warning display sections and to reduce cost.

FIG. 13 is a flowchart according to the fifth embodiment.

Also in this embodiment, the same steps as those in the first embodiment of FIG. 8 are denoted by the same reference numerals, and duplicate description will be omitted. On the other hand, this embodiment is an example in which there is no master warning display section in the driver's discrimination visual field as in the fourth embodiment. That is, if it is determined in step S51 that there is no master warning display section in the driver's discrimination field of view, a master warning warning display change is made in step S52, and in step S53 the background color change or blinking of the entire meter display section is performed. For example, the display of the master warning display is changed. Step S54 is a normal master warning display. Therefore, in this embodiment as well, the master warning display can be easily noticed by the driver in the peripheral visual field.

FIG. 14 shows an example of the master warning display in step S53. (A) shows the state before displaying the master warning, and (b) shows the state after displaying the master warning. The master warning display in (b) is obtained by changing the distribution colors of the entire meter display unit.

FIG. 15 is a flowchart according to the sixth embodiment.

In this embodiment, the driving state detecting means for detecting the driving state of the driver is provided, and the stimulus level of the master warning display is controlled according to the driver's driving operation concentration. The internal circuit of FIG. 2) functions as the operating state detecting means. That is, in step S61, it is determined whether or not there is a master warning display section in the driver's discrimination visual field. If there is no master warning display section in the discrimination visual field, the operation status is read in step S62. The reading of the driving situation is performed by, for example, accelerator opening, vehicle speed, shift operation,
This is based on detection signals such as a brake operation and a steering angle, and these are read as predetermined values. After the reading of the operation status is performed, step S63 is performed.
In, the determination of the degree of concentration of the driving operation is performed. This determination is based on the assumption that the user concentrates on driving operation when the read predetermined value exceeds a reference value stored in the controller in advance. The relationship between these reference values and the predetermined values is as follows.

Time derivative of accelerator opening a within a fixed time Σ (da / dt)> θ1 (S1 is a reference value) Time derivative of speed vΣ (dv / dt)> θ2 (S2 is a reference value) Time derivative of steering angle θ within a certain time (d
(θ / dt)> θ3 (S3 is a reference value) ・ The number of shift operations within a certain time is a certain number or more ・ The number of brake operations (or treading force) is a certain number of times (a certain value) or more If it is determined that there is, the stimulus level in the peripheral visual field of the master warning display is controlled in step S64.

Next, in step S65, a master warning display is performed with the stimulus level adjusted. In other words, the color for slightly lowering or changing the height of the brightness of the master warning display is not a color that changes extremely,
In the case where the color is felt as if it has changed a little, or the color is gradually changed, and furthermore, when blinking, an adjusted display such as making the blinking cycle gentle is performed. It should be noted that the master warning display may not be performed in step S65. Next, step S6
If it is determined in step 3 that the user is not concentrated on the driving operation, a normal master warning display is performed in step S66. Therefore, in this embodiment, the stimulus level of the master warning display can be adjusted according to the degree of concentration of the driving operation, and the degree of concentration of the driving operation can be maintained regardless of the master warning display.

FIG. 16 is a flowchart according to the seventh embodiment.

The seventh embodiment has substantially the same structure as the sixth embodiment, except that a physiological condition detecting means is provided in place of the operating condition detecting means provided in the sixth embodiment.
The internal circuit of the microcomputer 67 (FIG. 2) functions as operating state detecting means. That is, in step S62 of the sixth embodiment, the driving condition is read based on the accelerator opening and the like, whereas in the seventh embodiment, in step S62, the heart rate, the brain wave, the electrocardiogram, the driving time, the line-of-sight analyzer, etc. The operation status is read based on the detection signal. And in step S63,
The determination of the degree of concentration of the driving operation is based on whether or not the predetermined detection value exceeds a certain value stored in the controller. Specifically, ・ The number of blinks and eye closing time within a certain period of time are above a certain value ・ The amplitude value of the α wave component of the brain wave is above a certain value ・ Concentrate on driving operation when the RRV value of the heartbeat is above a certain value Judgment that it is not performed, ・ The number of blinks within a certain period of time or the eye closing time is a certain value or more ・ The amplitude value of the alpha wave component of the brain wave is a certain value or more Judge that you are concentrated on. This detects the driver's physiological state, such as drowsiness and fatigue,
Judgment of the degree of concentration on driving according to the physiological condition of the driver is performed. When the driver is concentrated on driving, the master warning display is not performed as in the sixth embodiment or the stimulus level is reduced so that the load on the driving operation is reduced. I do. When the driver is not concentrated on the driving operation, the driver can be encouraged to increase the degree of concentration at a stronger stimulation level.

FIG. 17 is a flowchart according to the eighth embodiment.

Also in this embodiment, the same steps as those in the first embodiment of FIG. 8 are denoted by the same reference numerals, and duplicate description will be omitted. On the other hand, in this embodiment, the master warning peripheral visual field display level is controlled in accordance with the urgency of the alarm display, and the state of the vehicle requiring the alarm detected by the driving state detection unit 2 (FIG. 2) is controlled. An urgency judging means for judging the urgency is provided, and an internal circuit of the microcomputer 67 (FIG. 2) constitutes the urgency judging means. That is, in step S71, it is determined whether or not there is a master warning display portion within the discrimination field of view of the driver. If it is determined that there is no master warning display portion, the process proceeds to step S72. In step S72, the urgency of the alarm is determined. For example, if the driver forgets to release the side brake, it must be dealt with immediately after the master warning is displayed, and the alarm device has a high degree of urgency. In addition, it is determined that the urgency of the washer fluid shortage is not so high. If it is determined that the degree of urgency is high, step S7
The process proceeds to 3 to control the master warning peripheral visual field display level. This control raises the stimulus level by slightly increasing the luminance of the master warning display. Next, in step S74, a master warning display is performed in a state where the stimulus level is high. If it is determined in step S72 that the urgency is not high, a normal master warning display is performed in step S75. Step S
In the case of 75, it is also possible to reduce the stimulus level such as lowering the brightness of the master warning display.

Therefore, in this embodiment, the master warning display can be changed depending on the difference in the degree of urgency of the alarm display. In particular, when the degree of urgency is high, the urgency is emphasized by a strong stimulus. be able to.

On the other hand, the display position judging means CL7 (FIG. 1), that is, the master warning optimum display position judging circuit 65 (FIG. 2) provides a line-of-sight direction corresponding to the line-of-sight position of the driver, a left-right direction of a plurality of display positions, and the like. Based on the angle between the up and down directions, an appropriate display position according to the line of sight position is determined, and thereby a master warning display can be performed. That is, the horizontal and vertical angles from the driver's gaze point to all the master warning display positions are calculated, and the discrimination visual field (up to 5 degrees vertically and horizontally) and the effective visual field (15 degrees vertically and 12 degrees vertically) are calculated.
Degrees), stable field of view (left-right angle 30-45 degrees, top 20-3)
(0 degree, lower 20 to 40 degrees) and the guide visual field (left / right angle 50 degrees, upper 40 degrees, lower 45 degrees) to determine an appropriate display position. Then, the master warning display is preferentially performed in the order of the discrimination visual field, the effective visual field, and so on. In this case, when a plurality of master warning display sections are in the same field of view, a display position having a smaller angle is extracted as an appropriate display position. Thereby, the master warning display can be performed more accurately according to the line of sight of the occupant.

Further, there are the following methods for calculating the gaze point of the driver. That is, the hip point is estimated from the position of the seat slide and the seat lifter, and the eye point coordinates are calculated from the hip point, the physique (height and sitting height) of the driver, the seat back angle, the seat slide and the position of the seat lifter.

More specifically, from the hip point coordinate values (X0, Y0, Z0) of the reference position of the seat slide (or seat lifter) to the hip point coordinates (X _n , Y _n , Z _n ) based on the current seat slide position. Coordinate conversion is performed according to the number n of changed notches.

The exchange formula is X _n = X 0, Y _n = Y 0 + n × A
_{y, Z n = Z0 + n} × A z (A y, A z correction coefficient) Next, hip point coordinates and the seat back angle determined now (theta) in view of the eye point coordinates (X _e,
Y _e , Z _e ) are calculated as follows.

X _e = X _n , Y _e = Y _n + L × sin θ, Z
_{e = Z n + L × cos} θ: change the status pattern of the iris position to identify whether the line of sight of the driver is looking at which region according to this way coordinates of the eye point obtained (L correction value of sitting height) or eye point coordinate values _{(X e, Y e, Z} e) using the representative coordinate position of each display position angle from to a plurality of master warning display unit L _a ~M _z, calculated in the horizontal direction and the vertical direction I do. As a result, a master warning display can be performed at a more accurate position.
